I usually avoid Indian blades but the Euromax Platinum gave me an outstanding shave in my Fatip testina gentile. A winner!
My cheap blades are:
Derby Premium
Derby Usta
Astra SS
Wow, on amazon.fr these blades cost me 9,99 euros for 100 blades. Everything is so expensive in BelgiumI would like to add Voskhods. Great Blades in my opinion. I can buy them here in Germany on amazon for 6Euros per 100 Blades. So 6ct. per blade which will last ~4 shaves for me. So ~1,5ct. per shave.
I would be dead before I worked my way through the rest of the 200 blades that you have, if I got as many shaves per blade as you! Wow!In my opinion, it's impossible to answer this. It should be calculated based on cost/shave for the person using the blade. For instance, I have 129 shaves on an Astra SP blade. The current cost/shave is $0.0005348837. Another person might toss their cheaper blade after only a few shaves.
I may consider Nacets after I use up the 200 Astra SPs I have.
Update on this: I've since found that the cheaper Astra SS blades work as well for me as the SPs, and the Treet DuraSharps work very well and last 4+ shaves before rusting.I've picked up 100 Astra SP blades from that company named after a river a couple months ago for $6.99 with free shipping. I haven't found a better deal.
I also ordered 100 Treet DuraSharps (platinum coated carbon steel blades) for $7.99 with free shipping from that same company. Also an excellent deal.
I lucked out finding 100 Asco platinum orange for $5.00 and I really like them right out of the gate, but they only last a few shaves. No complaints for the price!
